GROUP COMMON-PHYSICAL DOWNLINK CONTROL CHANNEL (GC-PDCCH) FOR TRIGGERING FEEDBACK FOR MULTIMEDIA BROADCAST MULTICAST SERVICE (MBMS) GROUP COMMON-PHYSICAL DATA SHARED CHANNELS (GC-PDSCHS)

Abstract:

A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station on a granting group common (GC)-physical downlink control channel (PDCCH), a multimedia broadcast multicast service (MBMS) downlink grant that schedules an MBMS transmission at each UE of a group of UEs that includes the UE. The method also includes receiving, from the base station on a triggering GC-PDCCH, a message indicating respective feedback resources for each UE of the group of UEs. The method further includes receiving, from the base station, the MBMS transmission. The method still further includes transmitting, to the base station via the feedback resources, a feedback report based on receiving the MBMS transmission.
